ADVERTISING AIPARATUS.

Application filed March 29, 1924. Serial No. 702,927.

To aZZ whom it may concern Be it known that I, CHRISTIAN GLEERUP- Mourns, a subject of the King of Denmark,"

and resident of Solyst, Horsens, Denmark, have invented a new and useful Improved Advertising Apparatus, of which the following 1s a specification.

Thls lnventlon relates to an advertlsifig apparatus showing the advertisements on the circumferential wall of a column or drum. whlch is polygonal in horizontal section and the fiat parallel wall faces of which consist of semi-transparent mirrors, behind which are superposed compartments containing each a certain article of manufacture which becomes :visible when the respective compartment is illuminated interiorly so that the mirror surface disappears.

The advertising column or drum is, sup ported on a stationary base on which it can be. rotated by means of a motor housed within that base. The high number of revolutions of the motor is suitably reduced by means of a gearing, by the intermediary of which three or more groovedrollers are rotated, the grooves'of which receive a ring connected with the advertising column. The rollers serve, thus, for carrying the column, as well as for. rotating it. The ring supported in the roller grooves is provided with projections forming contacts and co-operating with stationary contacts for closing the circuits of the lamps housed in the compartments, the arrangement being such, that the lamps are switched on in such a succession that all compartments are illuminated in a certain order and, therefore, all articles of manufacture contained therein are shown.

The invention is illustrated, by way of example, in the accompanying drawings, in which Figure 1 is a side-view of the advertising apparatus, partly in vertical section; Figure 2 is a horizontal section in the plane I AB of Figure 1; Figure 3 is ahorizontal section in the plane-C-D of Figure 1.

In Figure 1 a is the advertising column, the interior of which is divided into parallel vertical rows of superposed compartments 7), b 6 b ments are separated from one another by horizontal partition walls 01,41 (1 d and their rear walls are formed by a common cylinder 0. The column shown in the drawings by way of example is octagonal, but I wish it to be understood, that it may be hexagonal or quadrangular or triangular,

The superposed compartetc., etc., and also the number of the superposed compartments may be chosen as desired or required. I

The wall parts or faces of the drum consist of semi-transparent mirrors 6, 6 e", e which, thus, close the compartments at their front side. f is a kind of cornice ofthe column, and -g is a bottom ring or inner flange, bythe intermediary of which the column is affixed to a ring hof angular section, the horizontal part being connected with said ring and the vertical part enga ing the grooves of grooved rollers k, k}, aflixed to shafts Z, Z Z supported in bearings in and n, m and W and m and 41?. At the inner nds of said shafts are bevelwheels 0, 0 0 which mesh with a common bevel-wheel 7) secured to a central vertical shaft 9 driven by an electromotor u by the r and a large-cog-wheel 1 which is affixed to the shaft g. The whole arrangement and combination of parts above-described is carried by a base plate '0, and the gearing is besides covered by an annular lining 'w extending from the rim of the base plate '0- to the lower rim of the drum (1.

On the outer surface of the vertical part of the ring 1; are projections av, .03 which are arranged either only at a certain portion or at certain portions of said ring, or extend around the circumference thereof. These projections form contacts which c0- operate with a stationary contact y (Figure- 1) or with a plurality of such contacts, as.

y, y f, 3 y, Figure'3. The number of therotatory contacts depends on the number of the compartments to be illuminated successively, or on the number of the lamps respectively which are to be switched on,

and the number of the stationary countercontacts depends 0.1 the number of the compartments which 'tre to be illuminated at a time. 2, .2 2 2 are the electric incandescent lamps shown in Figme 1; each lamp is arranged in the upper part of the respective compartment, preferably at the ceiling thereof, and in frontof each lamp is an opaque screen a, 41. (1. a preventing theeyes of the lockers-on fronr being dazzled by the light of' the lamp. Each screen may bear" an inscription having reference to the article shown in the respective compartment. The return wires from the individual lamps, which are conducted downwards along the 55 ipaired. It is also impossible for an article inner surface of the cylinder 0, are combined,

finally to form a cable which is passed.

through a central bore of the shaft g and terminates at a contact member rotating together Wltl'l. this shaft. There is also, of

course, provided for it a stationary countering apparatus is as follows 1 i so that theentire 7 ready described, closing then "is, therefore,

The polygonal drum 0, is rotated slowly and incessantly by the motor at so thatwthe mirrors e, e, e rotate correspondingly and each looker-on sees himself and the surroundings under constantly changing angles. This state lasts as long as no lamp is switched on, but as the contacts a: and y close successively the circuits of the lamps a, 2 z either singly or in certain groups, the respective lamps are caused to light up whereby the compartments pertaining to the respective'lamps are illuminated, in consequence of which the respective semi-transparent mirrors become practically whollytransparent so that the articles contained in the respective compartments become visible. In this way all articles are successively exposed to 'view, without any necessity for a looker-on to change his place.

The number of revolutions of the motor is greatly reduced by the gearing described, especially by the worm-wheel gearing t, the pinion 1' and the cog-wheel 1', and the drum every article can be fully examined. The rotatory motion transmitted to the shaft g .by the cogheel r is transmitted further by the bevel-wheels p and o, the shafts l, 1 Z, Z and the rolls I0, 10 k to theri ng' drum with its contents is rotated correspondingly slowly. Now, of course, also the contacts w, 50 m are moved round and contact successively with the stationary ontacts y, 4 3 as althe respective circuits. I y e main advantages obtainable by the new constructionof the rotatory advertising apparatus are the following: a As the compartments are separated from one" another by opaque walls, thelight illuminating any. one of them cannot find access into any of the neighbouring compartments whereby the effect would be im lam accidentally becoming displaced and coming in contact with the inner surface of the appertaining mirror to check the rotatorymotion of the drum ascanoccur in rotatory advertising apparatus having stationary mirrors in front of the rotatory compartments. A very important feature resides in supporting the rotatory druni with its mirrors by grooved rollers forming at the same number of lamps switched on at a time,

rotated only so slowly that stationary counter-contact contacts which are provided in convenient position permit the. change of the wiring connectlons for the lamps so that the succession of their-switching on, as well as the be varied as desired.

I claim: 1. A rotary advertising apparatus comprising, vin combination, a vertical drum divided into compartments, semi-transparent, mirrors forming the peripheral walls of 35 said compartments and adapted to serve as mirrors showing the surroundings of the drum when the compartments are dark but displaying the inner of the compartments when the latter are illuminated; a source of light alternately illuminating and darking 'said compartments and means to rotate said drum.'
